GLUING-MACHINE FOR PAPER BOTTLES.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application filed. June 12, 1914. Serial No; 844,606.

To all whom it may concern:

Be it known that we, FRANK N. Wars and \VILLIAM C. WVEIS, citizens ofthe United States, residing at Monroe, in the county of Monroe and Stateof Michigan, have invented certain new and useful Improvements inGluing-Machines for Paper Bot ties; and we do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

Our invention relates to a machine for performing one of the steps inthe manufacture of a box or bottle composed of paper, cardboard or thelike, and is intended, more particularly, to rapidly and uniformly coatwith glue or similar adhesive the surfacesof certain of the overlappingflaps of a boxblank. These flaps comprise the end of the box, ashereinafter described, it being understood that the side-edges of theblank have by a separate operation been previously secured togetherinoperative form.

Our invention also consists in details of construction hereinafterdescribed and pointed out in the claims.

. Our invention consists of the devices, construction and arrangement ofparts hereinafter described, and shown andillustrated in theaccompanying drawings, in which Figure 1, is a front-elevation of ourmachine with one of the glue-pots hereinafter referred to shown insection; Fig. 2, a sideelevation of said machine with portionshereinafter referred to shown in section and showing the box-blankcarrier hereinafter referred to in its initial position; Fig. 3, thesame showing the box-blank carrier elevated to near the end of itsupward travel;

Fig. l, a top-plan-view of the same with the box-blank carrier loweredas shown in Fig. 2; Fig. 5, a side-elevation of the lock-piecehereinafter referred to designed to retain the adjustment of the feed ofthe semiliquid adhesive, and Fig. 6, an end-view of the box-blank as itis fed into the machine.

Like numerals and letters of reference indicate like parts throughoutthe drawings.

In the drawings, 1 is a frame across the top, of which is journaled asat 2 a shaft 3.

This shaft carries a driving-pulley 4, and, if

desired, a loose-pulley 5 as a means for throwingthe machine into or outof opera tion. Upon the shaft 3 are fixed two gluerolls 6, the upperrear surfaces of which fit closely into and revolve in the front lowerpart of glue boxes 7 The glue-pots or boxes are open at their front forthe reception of the rolls and have sides which overlap and fit closelyagainst the ends of the rolls. The bottoms of the boxes 7 are forwardlyand downwardly inclined and their sides have laterally projectingflanges 8 which engage and slide in guides 8 carried by the frame of themachine. The lower forward edge of the bottom of each of the boxes isadapted to contact with or to be moved away from the glue-roll anydesired distance to either stop the flow of the glue or to permit itsflow upon the side of the roll at such rate and in such quantity as maybe desired. The position of each glue-box relatively to its roll iscontrolled by means of an adjusting screw 10 engaged with a stationarypiece 1O carried by the frame and passing through a lug l0 projectingfrom the box. (See Figs. 2 and 3.) The lug 10 is engaged at oppositesides by shoulders or nuts on the screw 10 so that the inward. oroutward movement of this screw imparts a corresponding movement of theglue-box toward or away from its roll.

99 are stop-screws located at opposite sides of the adjusting screw 10,each having a shoulder 11.

12 is a plate pivoted as at 13 upon the shank of screw 9 and having anotch 14 and a notchl5 in its lower edge. (See Fig. 5.) Assuming thatthe three screws 99 10 are set to permit exactly the required flow ofthe adhesive and that it becomes necessary to stop the machine, it willof course be also necessary to stop the flow of glue. To accomplishthis, the screws 10 are set forward bringing the bottoms of the boxesinto close contact with the glue-rolls. To reopen the glue orifices toexactly the proper adjustment, it is'only necessary to throw the piece12 with its notches lle15 into engagement with the screws 9 -'10 and towithdraw the boxes by means of screws 10 until the pieces 12 contactwith the shoulders ll on the screws 10. Now the boxes are stopped attheir original adjustment, thus obviating the necessity for furtherexperiment or test. Under some conditions it is desirable to applypressure to the contents of the glue-pots. For this purpose we providefor each glue-pot a plunger 7 having a handle 7 and which moves with aworking fit in a cylinder 7 open at top and bottom and connected withthe chamber of the gluebox. The plunger is readily removable and: may beweighted as may be desired'to give the requisite pressure upon thesemi-liquid lue.

b In Fig. 6 is illustrated a box having-its end-flaps unclosed. Thatform of our machine here illustrated is designed to coat with glue theinner surfacesexposed in the drawing-of the flaps a-b. In the completedbox the surface a will adhere to the outer surface of the flaps 0 andthe surface I) will adhere to the outer surface of the flaps a, thusforming a closely sealed three-ply end. The two rolls 6 are of the samewidth and of the same distance apart as the flaps ab. A bracket 16 issecured to the top of a frame 17 which slides vertically in guides orways 18 secured to the front of the frame 1. Upon the top of the bracketis mounted a box 19, open at its ends and top, and arranged to slidehorizontally inguides or ways 20 secured to the bracket 16. The box isprovided with an adjusting stop-screw 21 which contacts with the outerend of the bracket 16 and limits the inward movement upon the flaps ab,it is necessary that-theseflaps be spread apart and in the same plane,

as shown in Fig. 6, and that the flaps c be "folded inwardly into thesameplane with the flaps aZ and out of the way. To accomplish this, weprovide the devices now to 'be'described. 22-22 are a pair of thin metalplates of the same width as the flaps 0, pivoted together at theirhorizontal meeting edges, as at 23, upon the end of a horizontal rod 2%fixed in a cross-bar 25, .extendingbetween the side members of theframe 1. The

plates 22 are respectively pivotally connected by means of toggle-bars26 with a block 27 which slides on the rod 24. A spring 28 pressingagainst the block 26 holds the block pressed normally forward so thattheplates 22 flare toward the open mouth of the blank d and in horizontalalinement therewith.

Now when the box 19 is pushed forward carrying with it the blank d withits flaps projecting in frontof the box 19, the side flaps a-b arecaught by the side margins of the plates 22 and are spread apart whilethe flaps flaps a-b apart and the flaps ctogether, all in a flatvertical plane, the plates 22 yielding tothis movement through thetoggles 2627 and the spring 28. At aboutthe instant that the flaps abhave been positioned as just described, the box 19 containing the paperbox is lifted vertically so that the exposed surface of the flaps a-Z)rub against the revolving gluey surfaces of the glue-rolls 6. Thislifting of the box 19 is accomplished by means of the mechanism now tobe described. 29 is a bar the lower-end of which is pivotally connectedas at 30 with the vertically sliding frame 17, the upper end of the barbeing pivotally connected as at 31 with the under side of the slidingbox 19. 32 is a pawl pivotally connected as at 33 with the bar 29 andsliding horizontally in a sleeve 34 fixed between the side members ofthe sliding frame 17. 35lisa sprocket-chain-running upon an uppersprocket-wheel 36 and a lower sprocketwheel 37. The upper sprocket-wheelis fixed upon a shaft 38 which carries at its outer end a sprocketwheel39 upon which runs. a sprocket-chain,

10 driven by a sprooketwheel 41 upon the shaft The sprocket-chain 35carries at regularintervals lugs 12.

hen the box 19 is pushed inwardly,,as above described, the bar 29 isswung on-its lower pivot, thus forcing the inner endof the pawl 32 intothe path of the upwardly travelinglugs 42 on the sprocket-chain 35. Nowthe first lug 42 which comes along catches'the :pawl, thus lifting theframe v17, carrying withit the bracket 16, the box 19 and the paper box.Thus the flaps a which are held" spread apart by the wings 22 until theyreach the glue-rolls, are

moved upwardly ag l y h glue-rolls 6. To prevent the flaps a-"*- fromadhering to the glue-rolls as the box 19 ascends, we providea small.roller 43' close to and above the glue-rolls, and

which holds the flaps away from the gluerolls after-the application ofthe glue. The" flaps a b having now been lifted to their uppermost pointand having been brought in contact with the revolving glue-rolls, itbecomes necessary to retractthe box 19 and to permit the parts to resumetheir initial position, ready for a repetition of'the operations thusfardescribed. To this end we provide the following devices: Upon the bar29 is journaled a roller 44 which, when the box 19 is pushed inwardly toits limit, assumes the position shown by the adjacent dotted line. Astheframe 17 with its burden clined surface of the piece 45, thus swingingthe bar 29 outwardly carrying with it at-its I upper end the box 19. andat the same time pulling the pawl 32 out of-enga-gement with that lug42. with whichv it happens to be-in I engagement. The frame 17 with itsap.- pendages immediately drop to their original position. To preventundue noise, jar or concussion from the fall of the frame 17 we providea dash-pot 46 having a piston 47 connected by rod 48 with the lower endof the frame 17, operating in the usual manner. When the pawl 32 istripped from lug 42 the box 19 has not been withdrawn upon its bracketthe requisite distance for the reception of a box cl. To obviate this weprovide a bar 49, pivoted at its lower end, as at 50, on a bracket 51,secured to one of the guides 18 and in the path of the roller 44. Thepivot or shaft-piece 50 carries, rigid therewith, an arm 52 which at itsupper end is connected by means of spring 53 with the frame of themachine in such manner that the bar 49 is held normally pressed inwardlyat its top. Now as the roller 44 ascends, it traverses the inner edge ofthe bar 49 which yields to the upward movement of the roller. When theroller 44 has passed above the upper end of the bar 49 the bar, thusreleased, springs inwardly so that the roller in its descent traversesthe outwardly inclined outer edge of the bar, thus swinging the upperend of the bar 29 outwardly the required distance. The parts are thusrestored to their initial position. The box 41 is now removed from theholder 19, and the machine is ready for a repetition ofthe abovedescribed operation. It will be seen that when the flaps ab moveupwardly out of contact with the plates 22, these plates, under thepressure of spring 28 will, unless v prevented, swing upon their pivotsinto the path of the falling flaps a?). To obviate this we provide aplate 54 having a limited sliding movement upon the frame of the machineand held,normally elevated by a spring 55. The plate has rigidlyconnected thereto an inwardly projecting finger 56. lVhen the box-blankcarrier 19 is at its lowermost position it strikes and holds depressedthe plate 54 with its fingers 56, as in Fig. 2. Then the carrier movesupwardly the plate 54 is released and is moved by its spring upwardlywith the inner end of the finger 56 touching the lower plate 23. Nowboth of the plates are held in the same vertical plane, as in Fig. 3,until they are released by the fall of the carrier 19 upon the plate 54.
